Patent EP-0220705-A2 (EP)
Inventor: KOIKE SHIN ICHI
IPC: H04L25/49
Filed: 1986-10-27
Abstract: The quadriphase phase modulation system comprises a serial to parallel (S/P) converter (1) for converting serial input data into one-symbol two-bit parallel data, and a waveform generator (6) for generating waveform information corresponding to a bit pattern created by the current symbol of the S/P converter (1) and a symbol prior to this current symbol. A memory (4) stores a first waveform determined by the current symbol and the symbol prior to the current symbol and a second waveform determined by the current symbol. Then, the memory (4) supplies the waveform corresponding to the current symbol in response to the waveform information. A digital to analog converter (5) converts signals from this memory (4) into analog signals. This system is capable of generating phase modulation signals which are narrow in bandwidth without the need for a band-limiting filter (Fig. 11).

Abstract: A polymerization process, especially a solution polymerization process, for the preparation of high molecular weight polymers of alpha-olefins less susceptible to yellowness is disclosed. The process comprises feeding monomer(s), coordination catalyst and optionally inert hydrocarbon solvent to a reactor, polymerizing the monomers at a temperature of up to 320°C and deactivating the catalyst. An organozirconium compound is admixed with the polymer thus obtained. The organozirconium compound is of the formula Zro m (OCOR') n -(OR")p. n  where R' and R" are independently selected from the group consisting of alkyl and cycloalkyl having 1-20 carbon atoms, and m = 0 or 1, provided that when m = 0, p is 4 and n is 0-4, and when m = 1, p is 2 and n = 0-2. Any hydrocarbon solvent and other volatile matter are then separated and a composition comprising said high molecular weight polymer is recovered. Alternatively the organozirconium compound may be blended with the polymer subsequent to the polymerization process. Examples of the high molecular weight polymers of alpha-olefins are homopolymers of ethylene, copolymers of ethylene with alpha-olefin homologues thereof, polypropylene and polybutene.

Abstract: Environmental heating/cooling systems are controlled by an interactive microprocessor and have continuous on-time and adaptive cycling modes wherein continuous on-time brings the temperature to a programmed set point and cycling precisely maintains that temperature rather than causing the temperature to oscillate between limits of a dead zone. Minimum pause and on-­time intervals of the cycling mode are established in accordance with optimum thermal transfer efficienty and/or equipment limitations. The initial cycle pause interval is a function of the degree transition time (i.e., time required for system to change temperature one degree as measured during continuous on-­time mode); the initial cycle on-time interval becomes the established minimum interval. Cycle intervals are modified as necessary to maintain the temperature at the set point with preference given to minimizing the cycle on-time interval. Hence, the cycle on-time interval is decreased to its established minimum before attempting to increase the cycle pause interval; conversely, the pause interval is decreased to its established minimum before increasing the cycle on-time interval. The system is predisposed to remain in the cycling mode whereby predetermined temperature variations from set point, in a direction opposed to system control, initiate a continuous on-­time to bring the temperature back   to set point, but only after attempting to do so with an additional modified cycle. Degree transition time and initial pause and on-time intervals are re-established during each continuous on-time mode. Cost savings are provided by cycling, as compared to continuous on-time, are periodically computed.
